Abstract (en)

[origin: WO2020028192A1] Systems, apparatus, and methods are described for additive manufacturing or three dimensional (3D) printing of objects using a set of physical masks. An additive manufacturing device can include one or more light sources, a vessel containing a volume of print material and a transparent base through which light can enter the vessel to cure a portion of the volume of print material, and a set of masks defining a series of patterns associated with layers of a 3D object that are each positionable between the light source and the transparent base to control a pattern of the light that is received through the transparent base and therefore the pattern of the cured portion of print material.
